Evaluation of exposure of workers at vibrations – hand arm

1 -INTRODUCTION

During our day-by-day we are exposed to vibration, one way or another, in cars, buses, train, etc. Many people are also exposed to other vibrations, during your work, for example those produced by hand tools, machines or heavy vehicles.

Here will be only referred to the undesirable vibrations: the effect of overexposure to vibration; the various factors that should be taken into account when it is measured, How is measured and evaluated, and what actions can be developed to reduce sources of harmful and/or dangerous vibrations.
